In this question there arose the issue of whether to take answers from various sources. I haven't seen the question of questions from students (obviously, presuming that a given question is in fact about math education). However, there has been some asking questioners about student status recently, which leads me to ask:
What information is appropriate to ask from questioners on this specific site?
Obviously on many sites it wouldn't be appropriate to ask job status, but given that this one is about teaching, it is reasonable that we ask the country people teach in, what age level, etc. On the other hand, unless the question is about gender or ethnicity (which they could be) probably ordinarily it wouldn't be appropriate to ask about this.
Although this question is motivated by asking whether questioners are students (and that raises the related question of whether we aren't all students!), I figure it would be helpful to have a big list of potential things to ask questioners about which mods and/or contributors think would be clearly off-limits or clearly on-topic.
